Description

本発明は、包装箱に関する。 The present invention relates to a packaging box.

特許文献１に記載された紙箱は、右側面板、前面板、左側面板および背面板を周方向に連設し、背面板に連設されたのりしろを右側面板の裏面に接着して筒形状を形成している。また、前面板の上端に連設された天面板が筒形状の上面を閉じながら、天面板の先端に連設された天面差込片が背面板に沿って筒形状の内側に差し込まれるようになっている。 The paper box described in Patent Document 1 has a right side panel, a front panel, a left side panel, and a back panel connected in the circumferential direction, and a glue tab connected to the back panel is glued to the back surface of the right side panel to form a cylindrical shape. In addition, while a top panel connected to the upper end of the front panel closes the top surface of the cylindrical shape, a top insertion piece connected to the tip of the top panel is inserted into the inside of the cylindrical shape along the back panel.

特開２０１８－７６０７８号公報JP 2018-76078 A

上記した紙箱では、筒形状に差し込まれる天面差込片がのりしろに干渉しないように、のりしろが右側面板の裏面に接着されていた。しかしながら、のりしろと右側面板との継目が右側面に表れてしまうため、例えば、紙箱の美粧性を考慮すると、のりしろを背面板に接着するように構成したいという要求があった。 In the above-mentioned paper box, the adhesive tab was glued to the back surface of the right side panel so that the top insert piece that was inserted into the cylindrical shape would not interfere with the adhesive tab. However, since the seam between the adhesive tab and the right side panel was visible on the right side, there was a demand for a configuration in which the adhesive tab could be glued to the back panel, for example, in consideration of the aesthetic appeal of the paper box.

仮に、のりしろを背面板に接着した場合、筒形状に差し込まれる天面差込片の先端がのりしろに干渉し（突き当り）、円滑な天面差込片の差し込みが阻害されることがあった。この場合、天面板を背面板の上端に連設し、天面差込片を前面板に沿って筒形状の内側に差し込むようにすれば、両者の干渉を防止することが可能だが、前面板と天面板との間に僅かな隙間があくことになり、やはり紙箱の美粧性が低下するという問題があった。また、他にも、設計の都合上、のりしろが前面板に接着され、天面板が背面板の上端に連設され、天面差込片が筒形状に差し込まれることも考えられ、この場合も、円滑な天面差込片の差し込みが阻害されることになっていた。 If the adhesive tab were glued to the back panel, the tip of the top insertion piece that is inserted into the tube would interfere with the adhesive tab (butt up), preventing the top insertion piece from being inserted smoothly. In this case, if the top panel is connected to the top end of the back panel and the top insertion piece is inserted into the inside of the tube along the front panel, it is possible to prevent the two from interfering with each other, but this creates a small gap between the front panel and the top panel, which again reduces the aesthetic appeal of the paper box. In addition, for design reasons, it is also possible that the adhesive tab is glued to the front panel, the top panel is connected to the top end of the back panel, and the top insertion piece is inserted into the tube, which also prevents the top insertion piece from being inserted smoothly.

本発明は、上記事情を考慮し、継代板との干渉を抑制しながら差込片を筒体に円滑に差し込むことができる包装箱を提供する。 Taking the above circumstances into consideration, the present invention provides a packaging box that allows the insertion piece to be smoothly inserted into the cylindrical body while minimizing interference with the transition plate.

本発明は、一対の端板と一対の側板とが交互に周方向に配置され、周方向の一端に位置する前記側板に連設される継代板が周方向の他端に位置する前記端板の裏面に接合され、軸方向の両端に一対の開口部を開口させる筒体と、前記継代板と非接合とされる前記端板の少なくとも軸方向の一端に連設され、少なくとも軸方向の一方の前記開口部を閉じる少なくとも１つの蓋板と、前記蓋板の自由端に連設され、前記継代板およびこれと接合とされた前記端板に沿って前記筒体の内部に差し込まれる少なくとも１つの差込片と、を備え、前記継代板の少なくとも軸方向の一方には、前記継代板と接合とされた前記端板の軸方向の一端よりも外側に向かって突出する案内凸部が設けられている。 The present invention comprises a cylinder in which a pair of end plates and a pair of side plates are alternately arranged in the circumferential direction, a transition plate connected to the side plate located at one end in the circumferential direction is joined to the back surface of the end plate located at the other end in the circumferential direction, and a pair of openings are opened at both ends in the axial direction, at least one cover plate connected to at least one axial end of the end plate not joined to the transition plate and closing at least one of the openings in the axial direction, and at least one insertion piece connected to the free end of the cover plate and inserted into the inside of the cylinder along the transition plate and the end plate joined to it, and at least one axial side of the transition plate is provided with a guide protrusion that protrudes outward beyond one axial end of the end plate joined to the transition plate.

この場合、前記継代板から周方向に延設され、前記継代板と接合とされた前記端板の裏面に対向する延長板と、前記延長板の先端から前記継代板と非接合とされる前記端板に向けて延設され、前記筒体の内部空間を仕切る仕切板と、前記仕切板の先端に連設され、前記継代板と非接合とされる前記端板の裏面に接合される接合片と、を更に備えてもよい。 In this case, the cylinder may further include an extension plate extending from the transition plate in the circumferential direction and facing the back surface of the end plate joined to the transition plate, a partition plate extending from the tip of the extension plate toward the end plate not joined to the transition plate and dividing the internal space of the cylinder, and a joining piece connected to the tip of the partition plate and joined to the back surface of the end plate not joined to the transition plate.

また、本発明は、底板と、一対の端板と一対の側板とが交互に前記底板の周縁部に立設され、一対の前記側板に連設される２つの継代板が一方の前記端板の裏面に接合され、軸方向の一端に開口部を開口させる筒体と、他方の前記端板の軸方向の一端に連設され、前記開口部を閉じる蓋板と、前記蓋板の自由端に連設され、前記継代板および一方の前記端板に沿って前記筒体の内部に差し込まれる差込片と、を備え、各々の前記継代板の軸方向の一方には、一方の前記端板の軸方向の一端よりも外側に向かって突出する案内凸部が設けられている。 The present invention also includes a bottom plate, a pair of end plates and a pair of side plates that are alternately erected on the periphery of the bottom plate, two transition plates connected to the pair of side plates that are joined to the back surface of one of the end plates, a cylinder that opens an opening at one axial end, a cover plate connected to one axial end of the other end plate that closes the opening, and an insertion piece connected to the free end of the cover plate and inserted into the inside of the cylinder along the transition plate and one of the end plates, and a guide protrusion is provided on one axial end of each of the transition plates that protrudes outward beyond one axial end of one of the end plates.

これらの場合、一対の前記側板の少なくとも軸方向の一端に連設され、前記開口部を閉じた前記蓋板の裏面に対向する少なくとも２つの内折板を更に備え、前記継代板の少なくとも軸方向の一端部において、軸方向に直交する幅方向の内側には前記案内凸部が突設され、幅方向の外側には相対的に凹んだ係合凹部が形成され、前記蓋板には、幅方向の両端から一対のＬ字状切目を入れることで、前記差込片に食い込むような一対の係合凸部が突設され、前記筒体の内部に差し込まれた前記差込片は、前記Ｌ字状切目の断面を前記内折板の裏面に対向し、前記差込片から抜け出した前記係合凸部は、前記係合凹部に配置されるとよい。 In these cases, at least two inner folding plates are provided that are connected to at least one axial end of the pair of side plates and face the back surface of the cover plate that closes the opening, and at least one axial end of the transition plate, the guide protrusion is protruded on the inside in the width direction perpendicular to the axial direction, and a relatively recessed engagement recess is formed on the outside in the width direction, and a pair of L-shaped cuts are made in the cover plate from both ends in the width direction to provide a pair of engagement protrusions that bite into the insertion piece, and the insertion piece inserted inside the cylinder has a cross section of the L-shaped cut facing the back surface of the inner folding plate, and the engagement protrusion that comes out of the insertion piece is placed in the engagement recess.

本発明によれば、継代板との干渉を抑制しながら差込片を筒体に円滑に差し込むことができる。 According to the present invention, the insertion piece can be smoothly inserted into the cylindrical body while minimizing interference with the transition plate.

図および図２を参照して、包装箱１および商品ケース９０について説明する。図１は包装箱１を使用する状態を示す斜視図である。図２は包装箱１のブランク１Ａを示す平面図である。 The packaging box 1 and the product case 90 will be described with reference to FIG. 1 and FIG. 2. FIG. 1 is a perspective view showing the packaging box 1 in use. FIG. 2 is a plan view showing the blank 1A of the packaging box 1.

［第１実施形態］
図１に示すように、第１実施形態に係る包装箱１は、これとは別体となる商品ケース９０の側面９４Ａに取り付けられる。包装箱１を取り付けた商品ケース９０は、複数積み重ねられて店頭等に展示される。包装箱１は、略直方体状を成す使用形態とされ、包装箱１の内部には、例えば、商品ケース９０に添えて顧客に贈られる景品（図示せず）が収容されている。包装箱１の表面（外面）には、例えば、景品や商品ケース９０に収容された商品（図示せず）の説明や広告等の情報が表示（印刷）されている。 [First embodiment]
As shown in Fig. 1, the packaging box 1 according to the first embodiment is attached to a side surface 94A of a product case 90 which is separate from the packaging box 1. A plurality of product cases 90 to which the packaging box 1 is attached are stacked and displayed in a storefront or the like. The packaging box 1 is used in a form forming a substantially rectangular parallelepiped shape, and the inside of the packaging box 1 contains, for example, a gift (not shown) to be given to a customer together with the product case 90. On the surface (outer surface) of the packaging box 1, for example, information such as a description of the gift or a product (not shown) contained in the product case 90, or an advertisement is displayed (printed).

［商品ケース］
図１を参照して、商品ケース９０について簡単に説明する。商品ケース９０は、配列させた複数の商品（例えば飲料缶等）を包むように包装する所謂ラップアラウンド形式の箱である。商品ケース９０は、一対の平面壁９１と一対の側面壁９２とを交互に連設させて角筒状を成している。一対の側面壁９２の両端には二対の内フラップ９３が連設され、一対の平面壁９１の両端には二対の外フラップ９４が連設されている。内フラップ９３が折り曲げられ、外フラップ９４が内フラップ９３に重なるように折り曲げられて接着される。商品ケース９０は一対の平面壁９１を上下方向に向けた姿勢とされ、上下一対の外フラップ９４は先端を突き合せ突き合わせて側面９４Ａを形成する。 [Product case]
The product case 90 will be briefly described with reference to FIG. 1. The product case 90 is a so-called wrap-around type box that wraps and packages a plurality of arranged products (e.g., beverage cans, etc.). The product case 90 is formed into a rectangular tube shape by alternately connecting a pair of flat walls 91 and a pair of side walls 92. Two pairs of inner flaps 93 are connected to both ends of the pair of side walls 92, and two pairs of outer flaps 94 are connected to both ends of the pair of flat walls 91. The inner flaps 93 are folded, and the outer flaps 94 are folded and bonded so as to overlap the inner flaps 93. The product case 90 is oriented such that the pair of flat walls 91 faces in the vertical direction, and the upper and lower pairs of outer flaps 94 butt their tips together to form side surfaces 94A.

［包装箱（ブランク）］
包装箱１は、図２に示すブランク１Ａから組み立てられる。ブランク１Ａは、１枚の板紙を抜型等で打ち抜いて形成されている。板紙は、例えば、表裏両面をコーティングした多層抄きの厚紙である。なお、図２は、包装箱１の表面（外面）側を示している。本明細書では、紙目と平行な方向を「紙目方向」と呼び、紙目方向に直交する方向を「直交方向」と呼ぶこととする。図面に示す「Ｘ」は「紙目方向」を示し、「Ｙ」は「直交方向」を示している。 [Packaging box (blank)]
The packaging box 1 is assembled from a blank 1A shown in Fig. 2. The blank 1A is formed by punching out a sheet of paperboard using a die or the like. The paperboard is, for example, a multi-layered thick paperboard coated on both sides. Note that Fig. 2 shows the front (outer) side of the packaging box 1. In this specification, the direction parallel to the grain is referred to as the "grain direction," and the direction perpendicular to the grain direction is referred to as the "orthogonal direction." In the drawings, "X" indicates the "grain direction," and "Y" indicates the "orthogonal direction."

図２に示すように、ブランク１Ａは、前端板１１と、後端板１２と、一対の側板１３と、継代板１４と、延長板１５と、仕切板１６と、接合片１７と、一対の蓋板２０と、一対の差込片２１と、４つの内折板２２と、を備えている。なお、本明細書では、前端板１１と後端板１２をまとめて説明する場合、単に「一対の端板１１，１２」と呼ぶこととする。また、図２において、一対の側板１３は、前端板１１を挟んで上下対称となる形状であるため、主に１つの側板１３について説明する。また、一対の蓋板２０および一対の差込片２１は、それぞれ、前端板１１を挟んで左右対称となる形状であるため、主に１つの蓋板２０および１つの差込片２１について説明する。さらに、４つ（二対）の内折板２２は、前端板１１を中心に９０度ずつ回転させたような形状であるため、主に１つの内折板２２について説明する。 As shown in FIG. 2, the blank 1A includes a front end plate 11, a rear end plate 12, a pair of side plates 13, a transition plate 14, an extension plate 15, a partition plate 16, a joint piece 17, a pair of cover plates 20, a pair of insert pieces 21, and four inner folding plates 22. In this specification, when the front end plate 11 and the rear end plate 12 are described together, they will be simply referred to as a "pair of end plates 11, 12". In addition, in FIG. 2, the pair of side plates 13 are symmetrical in the vertical direction with the front end plate 11 in between, so one side plate 13 will be mainly described. In addition, the pair of cover plates 20 and the pair of insert pieces 21 are symmetrical in the horizontal direction with the front end plate 11 in between, so one cover plate 20 and one insert piece 21 will be mainly described. Furthermore, the four (two pairs) inner folding plates 22 are shaped as if rotated 90 degrees around the front end plate 11, so one inner folding plate 22 will be mainly described.

＜前端板、後端板、側板＞
前端板１１および後端板１２は、概ね、直交方向（左右方向）を長辺とする長方形状に形成されている。一対の側板１３は、それぞれ、直交方向を長辺とする略長方形状に形成され、その紙目方向の寸法は、前端板１１の紙目方向の寸法よりも短く（例えば１／３程度）なっている。一対の端板１１，１２と一対の側板１３とは、交互に紙目方向（周方向）に一列に並設（配置）されている。一対の側板１３は、第１折曲線Ｌ１を介して前端板１１の紙目方向の両端に連設されている。後端板１２は、第２折曲線Ｌ２を介して図２で下方の側板１３に連設されている。なお、前端板１１と一対の側板１３との表面は、広告等の情報を印刷するための提示面となっている（図示せず）。また、提示面には、広告等の情報を印刷することに限らず、例えば、ＰＯＰ広告等の情報が提示面に貼付されたり、書き込まれたりしてもよい（図示せず）。 <Front end plate, rear end plate, side plate>
The front end plate 11 and the rear end plate 12 are generally formed in a rectangular shape with the long side in the orthogonal direction (left-right direction). The pair of side plates 13 are each formed in a substantially rectangular shape with the long side in the orthogonal direction, and the dimension in the grain direction is shorter (for example, about 1/3) than the dimension in the grain direction of the front end plate 11. The pair of end plates 11, 12 and the pair of side plates 13 are alternately arranged in a row in the grain direction (circumferential direction). The pair of side plates 13 are connected to both ends of the front end plate 11 in the grain direction via a first folding line L1. The rear end plate 12 is connected to the lower side plate 13 in FIG. 2 via a second folding line L2. The surfaces of the front end plate 11 and the pair of side plates 13 are presentation surfaces for printing information such as advertisements (not shown). In addition, the presentation surfaces are not limited to printing information such as advertisements, and for example, information such as POP advertisements may be pasted or written on the presentation surfaces (not shown).

（回動板、ロック片）
後端板１２には、直交方向の両端から中央に向かって一対の凹部１２Ａが凹設されている。各々の凹部１２Ａは略台形状に切り欠かれており、各々の凹部１２Ａには回動板２３が配置されている。一対の回動板２３は、ヒンジ線Ｌ１１を介して後端板１２の直交方向の両側に連設されている。一対のヒンジ線Ｌ１１は、後端板１２の紙目方向の先端から基端（図２の下方から上方）に向かって互いに接近するように傾斜している。このため、各々の回動板２３は、略台形状に形成されている。各々の回動板２３の直交方向の先端には、差込折線Ｌ１２を介してロック片２４が連設されている。各々の差込折線Ｌ１２は紙目方向と略平行に伸長し、各々のロック片２４は略長方形状に形成されている。各々の回動板２３には、紙目方向（幅方向）の両端から一対のＬ字状切目２３Ａを入れることで、ロック片２４に食い込むような一対のロック凸部２５が突設されている。一対のロック凸部２５が設けられることで、ロック片２４の基端部には括れ部２４Ａが形成されている。 (rotating plate, lock piece)
A pair of recesses 12A are recessed from both ends in the perpendicular direction toward the center in the rear end plate 12. Each recess 12A is cut out in a substantially trapezoidal shape, and a rotating plate 23 is disposed in each recess 12A. The pair of rotating plates 23 are connected to both sides of the rear end plate 12 in the perpendicular direction via a hinge line L11. The pair of hinge lines L11 are inclined so as to approach each other from the tip end of the rear end plate 12 in the grain direction toward the base end (from the bottom to the top in FIG. 2). Therefore, each rotating plate 23 is formed in a substantially trapezoidal shape. A lock piece 24 is connected to the tip end of each rotating plate 23 in the perpendicular direction via an insertion fold line L12. Each insertion fold line L12 extends substantially parallel to the grain direction, and each lock piece 24 is formed in a substantially rectangular shape. Each of the rotating plates 23 has a pair of L-shaped cuts 23A cut from both ends in the grain direction (width direction) to form a pair of locking protrusions 25 that protrude and bite into the locking pieces 24. By providing the pair of locking protrusions 25, a constricted portion 24A is formed at the base end of the locking piece 24.

（掛合片）
後端板１２の中央領域には、直交方向に伸長する掛合折線Ｌ１３の両端を結ぶように略Ｕ字状（コ字状）の切目線２６Ａが切り込まれ、掛合折線Ｌ１３と切目線２６Ａとで囲まれた範囲に掛合片２６が区画されている。掛合片２６は、略四角形状に形成され、掛合折線Ｌ１３を介して後端板１２に連設されている。掛合片２６の先端側には、略半円形状の指入れ穴２６Ｂが凹設されている。なお、指入れ穴２６Ｂは省略されてもよい。 (Hanging piece)
In the central region of the rear end plate 12, a substantially U-shaped score line 26A is cut so as to connect both ends of the hook fold line L13 extending in the perpendicular direction, and a hook piece 26 is defined in the area surrounded by the hook fold line L13 and the score line 26A. The hook piece 26 is formed in a substantially rectangular shape and is connected to the rear end plate 12 via the hook fold line L13. A substantially semicircular finger insertion hole 26B is recessed at the tip side of the hook piece 26. The finger insertion hole 26B may be omitted.

＜継代板＞
継代板１４は、第１折曲線Ｌ１を介して図２で上方（周方向の一端）に位置する側板１３に連設されている。継代板１４は、直交方向を長辺とする略長方形状に形成され、その紙目方向の寸法は、側板１３の紙目方向の寸法よりも短く（例えば１／２程度）なっている。詳細は後述するが、継代板１４は、後端板１２の先端部（自由端部）の裏面に接合（接着）される部位である。 <Subculture plate>
The joining plate 14 is connected to the side plate 13 located at the upper side (one end in the circumferential direction) in Fig. 2 via the first folding line L1. The joining plate 14 is formed in a substantially rectangular shape with the long side in the perpendicular direction, and the dimension in the grain direction of the joining plate 14 is shorter (for example, about 1/2) than the dimension in the grain direction of the side plate 13. The details will be described later, but the joining plate 14 is a part that is joined (bonded) to the back surface of the tip end portion (free end portion) of the rear end plate 12.

（案内凸部）
継代板１４の直交方向（軸方向）の両端部には、一対の案内凸部２７が突設されている。詳細には、継代板１４の直交方向の両端部において、一対の案内凸部２７は、継代板１４の紙目方向の先端側（図２で上半分程度）に突設されている。各々の案内凸部２７は、略台形状の突起である。また、継代板１４の直交方向の両端部において、紙目方向の基端側（図２で下半分程度）には、相対的に凹んだ一対の係合凹部２８が形成されている。各々の係合凹部２８は、実際に凹んでいるわけではなく、案内凸部２７が突設されることで相対的に凹んでいるように見える部分である。一対の案内凸部２７を除いた継代板１４の直交方向の寸法（一対の係合凹部２８間の距離）は、側板１３や後端板１２の直交方向の寸法（最大値）よりも僅かに短くなっている。案内凸部２７の突出寸法（係合凹部２８との段差）は、例えば約３ｍｍとされている。 (Guide protrusion)
A pair of guide protrusions 27 are protruding from both ends of the transition plate 14 in the orthogonal direction (axial direction). In detail, at both ends of the transition plate 14 in the orthogonal direction, the pair of guide protrusions 27 are protruding from the tip side (about the upper half in FIG. 2) of the transition plate 14 in the grain direction. Each guide protrusion 27 is a substantially trapezoidal protrusion. In addition, at both ends of the transition plate 14 in the orthogonal direction, a pair of relatively recessed engagement recesses 28 are formed on the base end side in the grain direction (about the lower half in FIG. 2). Each engagement recess 28 is not actually recessed, but is a portion that appears to be relatively recessed by the protruding guide protrusions 27. The dimension of the transition plate 14 in the orthogonal direction (the distance between the pair of engagement recesses 28) excluding the pair of guide protrusions 27 is slightly shorter than the dimension (maximum value) of the side plate 13 and the rear end plate 12 in the orthogonal direction. The protruding dimension of the guide protrusion 27 (the step between the guide protrusion 27 and the engagement recess 28) is set to, for example, about 3 mm.

＜延長板、仕切板、接合片＞
延長板１５は、継代板１４から紙目方向の一方（周方向）に延設されている。つまり、延長板１５は、継代板１４と一体に形成されている。延長板１５と継代板１４とを合わせた紙目方向の寸法は、前端板１１の紙目方向の寸法の略半分とされている。延長板１５は、直交方向を長辺とする略長方形状に形成され、その直交方向の寸法は、継代板１４や側板１３の直交方向の寸法よりも十分に短くなっている。仕切板１６は、第３折曲線Ｌ３を介して延長板１５の紙目方向の先端に連設されている。仕切板１６は、延長板１５と同一幅（直交方向の寸法）となる略長方形状に形成され、その紙目方向の寸法は、側板１３の紙目方向の寸法と同一とされている。接合片１７は、第４折曲線Ｌ４を介して仕切板１６の紙目方向の先端に連設されている。接合片１７は、仕切板１６から紙目方向の一方（図２で上方）に向かって幅狭くなる略台形状に形成されている。接合片１７の紙目方向の寸法は、仕切板１６の紙目方向の寸法の略半分とされている。 <Extension board, partition board, joint piece>
The extension plate 15 extends from the joining plate 14 in one direction (circumferential direction) in the grain direction. That is, the extension plate 15 is formed integrally with the joining plate 14. The dimension in the grain direction of the extension plate 15 and the joining plate 14 combined is approximately half the dimension in the grain direction of the front end plate 11. The extension plate 15 is formed in an approximately rectangular shape with the orthogonal direction as the long side, and the dimension in the orthogonal direction is sufficiently shorter than the dimensions in the orthogonal direction of the joining plate 14 and the side plate 13. The partition plate 16 is connected to the tip of the extension plate 15 in the grain direction via the third fold line L3. The partition plate 16 is formed in an approximately rectangular shape with the same width (dimension in the orthogonal direction) as the extension plate 15, and the dimension in the grain direction is the same as the dimension in the grain direction of the side plate 13. The joint piece 17 is connected to the tip of the partition plate 16 in the grain direction via the fourth fold line L4. The joint piece 17 is formed in a generally trapezoidal shape that narrows toward one side in the grain direction (upward in FIG. 2 ) from the partition plate 16. The dimension of the joint piece 17 in the grain direction is approximately half the dimension of the partition plate 16 in the grain direction.

＜蓋板、差込片＞
一対の蓋板２０は、第５折曲線Ｌ５を介して前端板１１の直交方向（軸方向）の両端に連設されている。蓋板２０は、前端板１１と同一幅（紙目方向の寸法）となる略長方形状に形成され、その直交方向の寸法は、側板１３の紙目方向の寸法と同一とされている。一対の差込片２１は、第６折曲線Ｌ６を介して一対の蓋板２０の直交方向の先端（自由端）に連設されている。差込片２１は、蓋板２０と同一幅（紙目方向の寸法）となる略長方形状に形成され、その直交方向の寸法は、蓋板２０の直交方向の寸法の略半分とされている。 <Cover plate, insert piece>
The pair of cover plates 20 are connected to both ends of the front end plate 11 in the orthogonal direction (axial direction) via a fifth fold line L5. The cover plate 20 is formed in a substantially rectangular shape with the same width (dimension in the grain direction) as the front end plate 11, and the dimension in the orthogonal direction is the same as the dimension in the grain direction of the side plate 13. The pair of insertion pieces 21 are connected to the ends (free ends) in the orthogonal direction of the pair of cover plates 20 via a sixth fold line L6. The insertion pieces 21 are formed in a substantially rectangular shape with the same width (dimension in the grain direction) as the cover plate 20, and the dimension in the orthogonal direction is approximately half the dimension in the orthogonal direction of the cover plate 20.

第６折曲線Ｌ６（蓋板２０と差込片２１との境界）の紙目方向の中央付近には、差込切目３０が切り込まれている。差込切目３０は、第６折曲線Ｌ６から差込片２１の側に突き出す台形状切目３０Ａと、台形状切目３０Ａの両端から第６折曲線Ｌ６上に延びる直線状切目３０Ｂと、で構成されている。蓋板２０には、台形状切目３０Ａを入れることで、差込片２１に食い込むような台形凸部３０Ｃが突設されている。差込切目３０の全長は、ロック片２４（回動板２３）の紙目方向（幅方向）の寸法よりも僅かに長くなっている。蓋板２０には、紙目方向（幅方向）の両端から一対のＬ字状切目２０Ａを入れることで、差込片２１に食い込むような一対の係合凸部３１が突設されている。一対の係合凸部３１が設けられることで、差込片２１の基端部には括れ部２１Ａが形成されている。 An insertion cut 30 is cut near the center of the sixth fold line L6 (the boundary between the cover plate 20 and the insertion piece 21) in the grain direction. The insertion cut 30 is composed of a trapezoidal cut 30A that protrudes from the sixth fold line L6 toward the insertion piece 21, and linear cuts 30B that extend from both ends of the trapezoidal cut 30A onto the sixth fold line L6. The trapezoidal cut 30A is cut into the cover plate 20, forming a trapezoidal protrusion 30C that bites into the insertion piece 21. The total length of the insertion cut 30 is slightly longer than the dimension of the lock piece 24 (rotating plate 23) in the grain direction (width direction). The cover plate 20 is cut into a pair of L-shaped cuts 20A from both ends in the grain direction (width direction), forming a pair of engagement protrusions 31 that bite into the insertion piece 21. A pair of engaging protrusions 31 is provided, forming a constricted portion 21A at the base end of the insertion piece 21.

＜内折板＞
４つの内折板２２は、それぞれ、第７折曲線Ｌ７を介して側板１３の直交方向（軸方向）の端部と蓋板２０の紙目方向（幅方向）の端部とに連設されている。前端板１１、側板１３、蓋板２０および内折板２２の角部が集まる部分には、円形の抜き穴Ｈが穿設されている。内折板２２は、概ね菱形状に形成されており、抜き穴Ｈから対角線上に延びる第８折曲線Ｌ８によって略二等分に区画されている。内折板２２の先端（自由端）において、側板１３との接続部の近傍には内折凸部３２が形成され、内折凸部３２から第８折曲線Ｌ８までの間は、内折凸部３２よりも一段凹んだ内折凹部３３とされている。なお、抜き穴Ｈは省略されてもよい。 <Inner folding plate>
The four inner folding plates 22 are connected to the end of the side plate 13 in the orthogonal direction (axial direction) and the end of the cover plate 20 in the grain direction (width direction) via the seventh fold line L7. A circular punch hole H is drilled at the part where the corners of the front end plate 11, the side plate 13, the cover plate 20, and the inner folding plate 22 gather. The inner folding plate 22 is formed in a roughly diamond shape and is divided into approximately two equal parts by the eighth fold line L8 extending diagonally from the punch hole H. At the tip (free end) of the inner folding plate 22, an inner folding convex portion 32 is formed near the connection with the side plate 13, and the portion between the inner folding convex portion 32 and the eighth fold line L8 is an inner folding concave portion 33 that is one step recessed from the inner folding convex portion 32. The punch hole H may be omitted.

なお、第１折曲線Ｌ１、第５～第７折曲線Ｌ５～Ｌ７、ヒンジ線Ｌ１１、差込折線Ｌ１２および掛合折線Ｌ１３は、それぞれ、板紙を表面から凹ませた汎用罫線である。第２～第４折曲線Ｌ２～Ｌ４および第８折曲線Ｌ８は、汎用罫線上にミシン目を形成したリード罫である。汎用罫線は、主に、裏面を内側に向けるように板紙を折り曲げる（正折りする）機能を有している。リード罫は、正折りし易くしたり、表面を内側に向けるように板紙を折り曲げたり（逆折りしたり）する機能を有している。上記した折曲線等は、汎用罫線やリード罫に限らず、例えば、ミシン目等、板紙を所望の向きに折り曲げるための線であれば如何なるものでもよい。 The first fold line L1, the fifth to seventh fold lines L5 to L7, the hinge line L11, the insertion fold line L12, and the hook fold line L13 are all-purpose creases that recess the paperboard from the front side. The second to fourth fold lines L2 to L4 and the eighth fold line L8 are lead creases that form perforations on the general-purpose creases. The general-purpose creases mainly function to fold the paperboard so that the back side faces inward (forward folding). The lead creases function to make forward folding easier and to fold the paperboard so that the front side faces inward (reverse folding). The fold lines and the like described above are not limited to general-purpose creases and lead creases, and may be any lines for folding the paperboard in a desired direction, such as perforations.

［包装箱の製造］
次に、図３Ａおよび図３Ｂを参照して、包装箱１の製造工程について簡単に説明する。図３Ａは包装箱１の製造工程を説明する斜視図である。図３Ｂは包装箱１を折り畳んだ状態を示す斜視図である。 [Manufacturing of packaging boxes]
Next, a brief description will be given of a manufacturing process of the packaging box 1 with reference to Figures 3A and 3B. Figure 3A is a perspective view illustrating the manufacturing process of the packaging box 1. Figure 3B is a perspective view showing the packaging box 1 in a folded state.

包装箱１は、例えば、自動製函機（図示せず）によって大量生産される。自動製函機には複数のブランク１Ａがセットされており、自動製函機はブランク１Ａを適所で折り曲げたり接着したりすることで包装箱１を製造する。 Packaging boxes 1 are mass-produced, for example, by an automatic box-making machine (not shown). A number of blanks 1A are set in the automatic box-making machine, and the automatic box-making machine produces packaging boxes 1 by folding and gluing the blanks 1A at appropriate positions.

図３Ａに示すように、自動製函機は、接合片１７の裏面に接着剤を塗布し（図２の斜線部および図３Ａの破線部を参照）、継代板１４を第１折曲線Ｌ１に沿って内側に折り返す（正折りする）。継代板１４、延長板１５、仕切板１６および接合片１７は、側板１３と前端板１１との裏面に重なり、接合片１７は、接着剤を介して前端板１１（継代板１４と非接合とされる端板）の裏面に接合される。 As shown in Figure 3A, the automatic box making machine applies adhesive to the back surface of the joint piece 17 (see the shaded area in Figure 2 and the dashed area in Figure 3A), and folds the transition plate 14 inward along the first fold line L1 (forward folding). The transition plate 14, extension plate 15, partition plate 16, and joint piece 17 overlap the back surfaces of the side plate 13 and front end plate 11, and the joint piece 17 is joined to the back surface of the front end plate 11 (the end plate not joined to the transition plate 14) via adhesive.

続いて、図３Ｂに示すように、自動製函機は、後端板１２の自由端側の裏面に接着剤を塗布し（図２の斜線部および図３Ｂの破線部を参照）、後端板１２に隣接する側板１３を第１折曲線Ｌ１に沿って内側に折り返す（正折りする）。後端板１２および側板１３は、先に折り返した各板１４～１７の表面に重なり、後端板１２の自由端側は、接着剤を介して継代板１４の表面に接合される。換言すれば、紙目方向（周方向）の一端に位置する側板１３に連設された継代板１４が、紙目方向（周方向）の他端に位置する後端板１２の裏面に接合される。継代板１４の軸方向の両側に設けられた一対の案内凸部２７は、継代板１４と接合とされた後端板１２の軸方向の両端よりも外側に向かって突出している。一対の案内凸部２７を除いた継代板１４の軸方向の両端（一対の係合凹部２８を形成する両縁）は、後端板１２の軸方向の両端よりも僅かに内側に位置している。 Next, as shown in FIG. 3B, the automatic box making machine applies adhesive to the back surface of the free end side of the rear end plate 12 (see the hatched portion in FIG. 2 and the dashed portion in FIG. 3B), and folds the side plate 13 adjacent to the rear end plate 12 inward along the first fold line L1 (forward folding). The rear end plate 12 and the side plate 13 overlap the surfaces of the previously folded plates 14-17, and the free end side of the rear end plate 12 is joined to the surface of the transition plate 14 via adhesive. In other words, the transition plate 14 connected to the side plate 13 located at one end in the grain direction (circumferential direction) is joined to the back surface of the rear end plate 12 located at the other end in the grain direction (circumferential direction). A pair of guide protrusions 27 provided on both sides in the axial direction of the transition plate 14 protrude outward from both ends in the axial direction of the rear end plate 12 joined to the transition plate 14. Both axial ends of the transition plate 14 (the edges that form the pair of engagement recesses 28) excluding the pair of guide protrusions 27 are located slightly inward from both axial ends of the rear end plate 12.

以上によって、平坦に折り畳まれた包装箱１が完成する。 This completes the flat folded packaging box 1.

［包装箱の組立（封緘）］
次に、図４ないし図６を参照して、包装箱１の組立手順（封緘手順）について説明する。図４は筒体１０を形成した状態を示す斜視図である。図５は開口部１０Ａを閉じる過程を示す斜視図である。図６は開口部１０Ａを閉じた状態を示す斜視図である。 [Assembly of packaging boxes (sealing)]
Next, the assembly procedure (sealing procedure) of the packaging box 1 will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a perspective view showing the state in which the cylindrical body 10 has been formed. Fig. 5 is a perspective view showing the process of closing the opening 10A. Fig. 6 is a perspective view showing the state in which the opening 10A is closed.

＜筒体の組立＞
図４に示すように、作業者は、折り畳まれた包装箱１（図３Ｂ参照）の一対の側板１３を引き起こして、一対の端板１１，１２と一対の側板１３とを略直交させる。これにより、一対の端板１１，１２と一対の側板１３とが交互に周方向に配置され、角筒状の筒体１０が形成される。一対の端板１１，１２は内部空間１０Ｂを挟んで厚み方向に対向し、一対の側板１３は内部空間１０Ｂを挟んで幅方向に対向する。筒体１０の軸方向の両端には、一対の開口部１０Ａが開口している。 <Assembly of the cylinder>
As shown in Fig. 4, the worker raises the pair of side plates 13 of the folded packaging box 1 (see Fig. 3B) so that the pair of end plates 11, 12 and the pair of side plates 13 are substantially perpendicular to each other. As a result, the pair of end plates 11, 12 and the pair of side plates 13 are alternately arranged in the circumferential direction to form a rectangular cylindrical body 10. The pair of end plates 11, 12 face each other in the thickness direction with an internal space 10B therebetween, and the pair of side plates 13 face each other in the width direction with an internal space 10B therebetween. A pair of openings 10A are opened at both ends in the axial direction of the cylindrical body 10.

筒体１０を形成する過程で、仕切板１６は、延長板１５に対して第３折曲線Ｌ３に沿って略直角に正折りされ、接合片１７に対して第４折曲線Ｌ４に沿って略直角に逆折りされる。この状態で、延長板１５は、後端板１２（継代板１４と接合とされた端板）の裏面に対向している。仕切板１６は、延長板１５の先端から前端板１１（継代板１４と非接合とされる端板）に向けて延設されている。仕切板１６は、後端板１２の内側に積層された延長板１５と、前端板１１に接合された接合片１７との間に架設され、筒体１０の内部空間１０Ｂを略二分割に仕切る。 In the process of forming the cylindrical body 10, the partition plate 16 is folded forward at approximately a right angle to the extension plate 15 along the third fold line L3, and folded backward at approximately a right angle to the joint piece 17 along the fourth fold line L4. In this state, the extension plate 15 faces the back surface of the rear end plate 12 (the end plate joined to the transition plate 14). The partition plate 16 extends from the tip of the extension plate 15 toward the front end plate 11 (the end plate not joined to the transition plate 14). The partition plate 16 is installed between the extension plate 15 stacked on the inside of the rear end plate 12 and the joint piece 17 joined to the front end plate 11, and divides the internal space 10B of the cylindrical body 10 into approximately two parts.

＜開口部の閉塞＞
作業者は、筒体１０の軸方向の一方の開口部１０Ａを蓋板２０で閉塞する。具体的には、図４に示すように、作業者は、幅方向両側の内折板２２を第７折曲線Ｌ７で正折りし、かつ第８折曲線Ｌ８で逆折りしながら、蓋板２０を第５折曲線Ｌ５に沿って正折りする。図５に示すように、内折板２２は、第８折曲線Ｌ８で二重に折り重ねられ、蓋板２０は、内折板２２を押し込みながら、軸方向の一方の開口部１０Ａを閉じる。また、作業者は、差込片２１を第６折曲線Ｌ６に沿って正折りして継代板１４およびこれと接合とされた後端板１２に沿って筒体１０の内部に差し込む。詳細には、差込片２１を第６折曲線Ｌ６で正折りすると、蓋板２０の一対の係合凸部３１および台形凸部３０Ｃが差込片２１から抜け出して相対的に突出し、一対の係合凸部３１および台形凸部３０Ｃが抜け出した跡には僅かな隙間（スリット）が開口する（図４および図５参照）。差込片２１は、その先端部を案内凸部２７の裏面に接触させながら、後端板１２（継代板１４）の裏面と内折板２２の上端との隙間を通って筒体１０の内部に差し込まれる（図４および図５参照）。 <Blocking of openings>
The worker closes one of the openings 10A in the axial direction of the cylindrical body 10 with the cover plate 20. Specifically, as shown in FIG. 4, the worker folds the inner folding plates 22 on both sides in the width direction forward at the seventh folding line L7 and reversely folds them at the eighth folding line L8, while folding the cover plate 20 forward along the fifth folding line L5. As shown in FIG. 5, the inner folding plate 22 is folded twice at the eighth folding line L8, and the cover plate 20 closes one of the openings 10A in the axial direction while pushing the inner folding plate 22. In addition, the worker folds the insertion piece 21 forward along the sixth folding line L6 and inserts it into the inside of the cylindrical body 10 along the joining plate 14 and the rear end plate 12 joined thereto. In detail, when the insertion piece 21 is folded forward at the sixth fold line L6, the pair of engaging protrusions 31 and the trapezoidal protrusion 30C of the cover plate 20 come out of the insertion piece 21 and protrude relatively, and a small gap (slit) opens at the place where the pair of engaging protrusions 31 and the trapezoidal protrusion 30C came out (see Figures 4 and 5). The insertion piece 21 is inserted into the inside of the cylinder 10 through the gap between the back surface of the rear end plate 12 (transition plate 14) and the upper end of the inner folding plate 22 while making contact with the back surface of the guide protrusion 27 (see Figures 4 and 5).

図６に示すように、差込片２１全体が筒体１０の内部に差し込まれ、蓋板２０が開口部１０Ａを閉塞した状態で、差込片２１は、括れ部２１Ａを一対の内折板２２の内折凹部３３間に嵌め込み、Ｌ字状切目２０Ａの断面を内折板２２の内折凸部３２の裏面に対向させている（係合させている）（図示せず）。また、差込片２１から抜け出した係合凸部３１は、継代板１４の係合凹部２８に配置されている（図５および図６参照）。係合凸部３１は、継代板１４の係合凹部２８を形成する両縁（後端板１２の軸方向の一端）に対向し、案内凸部２７と噛み合うように配置される。なお、幅方向両側の２つの内折板２２は、開口部１０Ａを閉じた蓋板２０の裏面に対向する（図５参照）。 As shown in FIG. 6, when the entire insertion piece 21 is inserted into the inside of the cylinder 10 and the cover plate 20 closes the opening 10A, the insertion piece 21 fits the constricted portion 21A between the inner folding recesses 33 of the pair of inner folding plates 22, and the cross section of the L-shaped cut 20A faces (engages) with the back surface of the inner folding protrusion 32 of the inner folding plate 22 (not shown). In addition, the engagement protrusion 31 that has come out of the insertion piece 21 is arranged in the engagement recess 28 of the transition plate 14 (see FIG. 5 and FIG. 6). The engagement protrusion 31 faces both edges (one end in the axial direction of the rear end plate 12) that form the engagement recess 28 of the transition plate 14, and is arranged to engage with the guide protrusion 27. In addition, the two inner folding plates 22 on both sides in the width direction face the back surface of the cover plate 20 that closes the opening 10A (see FIG. 5).

次に、作業者は、回動板２３をヒンジ線Ｌ１１に沿って跳ね上げながら（逆折りしながら）、ロック片２４を差込折線Ｌ１２に沿って正折りし、ロック片２４の先端を差込切目３０（台形凸部３０Ｃが抜け出してできたスリット）に向ける（図５参照）。作業者は、ヒンジ線Ｌ１１まわりに跳ね上げた回動板２３を元に戻しながら、ロック片２４を差込切目３０に差し込む（図６参照）。ロック片２４は、括れ部２４Ａを台形状切目３０Ａに嵌め込み、Ｌ字状切目２３Ａの断面を直線状切目３０Ｂの縁部（差込片２１の裏面）に対向（係合）させている（図示せず）。一対のロック凸部２５と台形凸部３０Ｃとは、互いに噛み合うように係合している。 Next, while flipping up the rotating plate 23 along the hinge line L11 (folding it backwards), the worker folds the locking piece 24 forward along the insertion fold line L12 and orients the tip of the locking piece 24 toward the insertion slit 30 (the slit created by the escape of the trapezoidal protrusion 30C) (see FIG. 5). The worker inserts the locking piece 24 into the insertion slit 30 while returning the rotating plate 23 flipped up around the hinge line L11 (see FIG. 6). The locking piece 24 fits the constricted portion 24A into the trapezoidal slit 30A, and the cross section of the L-shaped slit 23A faces (engages) with the edge of the linear slit 30B (the back surface of the insertion piece 21) (not shown). The pair of locking protrusions 25 and the trapezoidal protrusion 30C are engaged so as to mesh with each other.

以上によって、筒体１０の軸方向の一方の開口部１０Ａは蓋板２０で閉塞され、差込片２１はロック片２４等によって筒体１０から容易に引き抜けない状態になる（図６参照）。また、ヒンジ線Ｌ１１が斜めに形成されているため、回動板２３が跳ね上がり難く、ロック片２４が引き抜き難くなっている。 As a result, one opening 10A in the axial direction of the cylinder 10 is closed by the cover plate 20, and the insertion piece 21 cannot be easily pulled out of the cylinder 10 by the lock piece 24, etc. (see Figure 6). In addition, because the hinge line L11 is formed at an angle, the rotating plate 23 does not easily jump up, and the lock piece 24 is difficult to pull out.

＜景品の収容および封緘＞
作業者は、筒体１０の軸方向の他方の開口部１０Ａから、仕切板１６で仕切られた内部空間１０Ｂに１つまたは２つの景品を収容する。作業者は、筒体１０に景品を収容した後、上記した一方の開口部１０Ａの閉塞手順と同一の手順で、他方の開口部１０Ａを閉塞する（後述する図７参照）。 ＜Storage and sealing of prizes＞
The worker places one or two prizes in the internal space 10B separated by the partition plate 16 from the other opening 10A in the axial direction of the cylinder 10. After placing the prizes in the cylinder 10, the worker closes the other opening 10A in the same procedure as the above-mentioned closing procedure for one opening 10A (see FIG. 7 described later).

以上によって、包装箱１の組立（封緘）が完了する。なお、上記した包装箱１の組立手順（封緘手順）では、筒体１０の軸方向の一方の開口部１０Ａを閉塞した後に景品を収容していたが、これに限らず、例えば、筒体１０を形成した後に景品を収容し、その後、軸方向の両方の開口部１０Ａを閉塞してもよい。 This completes the assembly (sealing) of the packaging box 1. Note that in the above-described assembly procedure (sealing procedure) of the packaging box 1, the prize is placed inside after one of the axial openings 10A of the cylindrical body 10 is closed, but this is not limited thereto. For example, the prize may be placed inside after the cylindrical body 10 is formed, and then both axial openings 10A may be closed.

［包装箱の取付］
次に、図１および図７を参照して、作業者は、景品を収容した包装箱１を商品ケース９０の側面９４Ａに取り付ける。図７は掛合片２６を開いた状態を示す斜視図である。 [Installation of packaging box]
1 and 7, the worker attaches the packaging box 1 containing the gift to the side surface 94A of the product case 90. Fig. 7 is a perspective view showing the state in which the hook piece 26 is open.

図１に示すように、包装箱１は、一対の側板１３を上下方向に向け、前端板１１を正面に向け、後端板１２の掛合片２６を介して商品ケース９０の側面９４Ａに取り付けられる。図７に示すように、作業者は、指入れ穴２６Ｂに指を掛け、掛合片２６を切目線２６Ａに沿って切断しながら掛合折線Ｌ１３で外側に折り曲げる。作業者は、掛合片２６の先端部（下端部）を商品ケース９０の一対の外フラップ９４の突き合せ部分の隙間に差し込み、掛合片２６を下方の外フラップ９４に引っ掛ける。これにより、包装箱１が商品ケース９０の側面９４Ａに仮に固定される。 As shown in FIG. 1, the packaging box 1 is attached to the side 94A of the product case 90 via the hook piece 26 of the rear end plate 12, with the pair of side plates 13 facing up and down and the front end plate 11 facing forward. As shown in FIG. 7, the worker hooks his finger into the finger hole 26B and bends the hook piece 26 outward at the hook fold line L13 while cutting along the cut line 26A. The worker inserts the tip (lower end) of the hook piece 26 into the gap between the butted parts of the pair of outer flaps 94 of the product case 90, and hooks the hook piece 26 onto the lower outer flap 94. This temporarily fixes the packaging box 1 to the side 94A of the product case 90.

次に、作業者は、包装箱１を上下方向に横断するように商品ケース９０の上下一対の平面壁９１に渡って透明な粘着テープ（図示せず）を貼り付ける。これにより、包装箱１が商品ケース９０の側面９４Ａに固定される（図１参照）。 Next, the worker applies transparent adhesive tape (not shown) across the pair of upper and lower flat walls 91 of the product case 90 so as to cross the packaging box 1 in the vertical direction. This fixes the packaging box 1 to the side 94A of the product case 90 (see FIG. 1).

以上説明した第１実施形態に係る包装箱１では、継代板１４が、継代板１４と接合とされた後端板１２の軸方向の両端よりも両外側に向かって突出した一対の案内凸部２７を有する構成とした。この構成によれば、差込片２１の先端が継代板１４の先端に突き当たることが防止され、差込片２１を案内凸部２７の裏面に接触させながら筒体１０の内部に差し込むことができる。これにより、案内凸部２７が差込片２１を筒体１０に差し込む際のガイドとして利用されるため、継代板１４との干渉を抑制しながら差込片２１を筒体１０に円滑に差し込むことができる。また、継代板１４および差込片２１等が後端板１２の側に集約されているため、前端板１１を継目のない平面とすることができる。これにより、商品ケース９０の側面９４Ａに包装箱１を取り付けた際に、包装箱１の美粧性を向上させることができると共に、前端板１１および一対の側板１３を広告や情報の提示面として利用することができる。 In the packaging box 1 according to the first embodiment described above, the transition plate 14 has a pair of guide protrusions 27 that protrude outward from both axial ends of the rear end plate 12 joined to the transition plate 14. This configuration prevents the tip of the insertion piece 21 from hitting the tip of the transition plate 14, and the insertion piece 21 can be inserted into the inside of the tube 10 while contacting the back surface of the guide protrusions 27. As a result, the guide protrusions 27 are used as a guide when inserting the insertion piece 21 into the tube 10, so that the insertion piece 21 can be smoothly inserted into the tube 10 while suppressing interference with the transition plate 14. In addition, since the transition plate 14 and the insertion piece 21 are concentrated on the rear end plate 12 side, the front end plate 11 can be made into a seamless flat surface. As a result, when the packaging box 1 is attached to the side surface 94A of the product case 90, the cosmetic properties of the packaging box 1 can be improved, and the front end plate 11 and the pair of side plates 13 can be used as surfaces for presenting advertisements and information.

また、第１実施形態に係る包装箱１によれば、接合片１７を後端板１２の裏面に接合し、前端板１１の先端部を継代板１４に接合し、一対の側板１３と仕切板１６とを引き起こすことで、内部空間１０Ｂが２つに仕切られた筒体１０を形成することができる。これにより、仕切りを別部材とする場合に比べて、簡単に包装箱１を組み立てることができる。 In addition, with the packaging box 1 according to the first embodiment, the joining piece 17 is joined to the back surface of the rear end plate 12, the tip of the front end plate 11 is joined to the transition plate 14, and the pair of side plates 13 and the partition plate 16 are raised to form a tubular body 10 in which the internal space 10B is divided into two. This makes it easier to assemble the packaging box 1 than when the partition is a separate member.

また、第１実施形態に係る包装箱１によれば、筒体１０の内部に差し込まれた差込片２１がＬ字状切目２０Ａの断面を内折板２２の裏面に係合させるため、筒体１０の内部に差し込まれた差込片２１を引き抜き難くすることができる。また、差込片２１から抜け出した係合凸部３１が係合凹部２８に嵌り込むため、包装箱１を封緘した状態で案内凸部２７を目立ち難くすることができ、包装箱１の美粧性を高めことができる。 In addition, according to the packaging box 1 of the first embodiment, the insertion piece 21 inserted into the inside of the cylindrical body 10 engages the cross section of the L-shaped cut 20A with the back surface of the inner folding plate 22, making it difficult to pull out the insertion piece 21 inserted into the inside of the cylindrical body 10. In addition, the engagement protrusion 31 that comes out of the insertion piece 21 fits into the engagement recess 28, making it possible to make the guide protrusion 27 less noticeable when the packaging box 1 is sealed, thereby improving the aesthetic appeal of the packaging box 1.

なお、第１実施形態に係る包装箱１では、継代板１４の軸方向の両端部に一対の案内凸部２７が突設されていたが、本発明はこれに限定されない。案内凸部２７は、継代板１４の少なくとも軸方向の一方に設けられ、継代板１４と接合とされた後端板１２の軸方向の一端よりも外側に向かって突出すればよい（図示せず）。 In the packaging box 1 according to the first embodiment, a pair of guide protrusions 27 protrude from both axial ends of the transition plate 14, but the present invention is not limited to this. The guide protrusions 27 may be provided on at least one axial end of the transition plate 14 and may protrude outward beyond one axial end of the rear end plate 12 joined to the transition plate 14 (not shown).

また、第１実施形態に係る包装箱１では、一対の蓋板２０が、継代板１４と非接合とされる前端板１１の軸方向の両端に連設されていたが、本発明はこれに限定されない。例えば、蓋板２０は、前端板１１の軸方向の一端のみに連設され、前端板１１の軸方向の他端では省略されてもよい。すなわち、筒体１０の軸方向の他方の開口部１０Ａは開放されていてもよく、この場合には、軸方向の他方に位置する差込片２１、内折板２２、回動板２３およびロック片２４等も省略してもよい。このように、蓋板２０（および差込片２１）は、前端板１１の少なくとも軸方向の一端に連設され、軸方向の一方の開口部１０Ａを閉じることができればよい。また、筒体１０の軸方向の他方の開口部１０Ａは、蓋板２０等とは異なる構造で閉塞されてもよい。具体的な一例として、所謂Ａ形式の段ボール箱のように、一対の側板１３の軸方向の他端に連設された一対の内フラップと、一対の端板１１，１２の軸方向の他端に連設された一対の外フラップとを順に折り重ね、一対の外フラップの突き合わせ部に粘着テープ等を貼付することで、開口部１０Ａを閉塞してもよい（図示せず）。また、他方の開口部１０Ａを閉塞する構造は、地獄底（アメリカンロック）であってもよいし、筒体１０を形成する過程で自動的に形成されるワンタッチ底であってもよい（いずれも図示せず）。 In addition, in the packaging box 1 according to the first embodiment, a pair of cover plates 20 are connected to both ends of the front end plate 11 in the axial direction, which is not joined to the transition plate 14, but the present invention is not limited to this. For example, the cover plate 20 may be connected only to one end of the front end plate 11 in the axial direction, and may be omitted at the other end of the front end plate 11 in the axial direction. That is, the other opening 10A in the axial direction of the cylindrical body 10 may be opened, and in this case, the insertion piece 21, the inner folding plate 22, the rotating plate 23, the lock piece 24, etc. located on the other side of the axial direction may also be omitted. In this way, the cover plate 20 (and the insertion piece 21) is connected to at least one end of the front end plate 11 in the axial direction, and it is sufficient that one opening 10A in the axial direction can be closed. In addition, the other opening 10A in the axial direction of the cylindrical body 10 may be closed with a structure different from the cover plate 20, etc. As a specific example, like a so-called Type A cardboard box, a pair of inner flaps connected to the other axial ends of a pair of side panels 13 and a pair of outer flaps connected to the other axial ends of a pair of end panels 11, 12 are folded over in order, and adhesive tape or the like is applied to the butted portion of the pair of outer flaps to close the opening 10A (not shown). In addition, the structure for closing the other opening 10A may be a locking bottom (American lock) or a one-touch bottom that is automatically formed during the process of forming the cylindrical body 10 (neither is shown).

また、第１実施形態に係る包装箱１では、内折板２２が側板１３と蓋板２０とに連設されていたが、本発明はこれに限定されない。内折板２２は、側板１３の軸方向の端部に連設され、蓋板２０とは分離されていてもよい（図示せず）。また、例えば、上記したように、他方の開口部１０Ａが蓋板２０等とは異なる構造で閉塞される場合、軸方向の他方の内折板２２は省略されてもよい（図示せず）。つまり、少なくとも２つの内折板２２が、一対の側板１３の少なくとも軸方向の一端に連設されていればよい。 In addition, in the packaging box 1 according to the first embodiment, the inner folding plate 22 is connected to the side plate 13 and the cover plate 20, but the present invention is not limited to this. The inner folding plate 22 may be connected to the axial end of the side plate 13 and separated from the cover plate 20 (not shown). Also, for example, as described above, if the other opening 10A is closed by a structure different from the cover plate 20, the other inner folding plate 22 in the axial direction may be omitted (not shown). In other words, it is sufficient that at least two inner folding plates 22 are connected to at least one axial end of a pair of side plates 13.

また、第１実施形態に係る包装箱１では、延長板１５、仕切板１６および接合片１７が設けられていたが、これに限らず、これらは省略されてもよい（図示せず）。つまり、筒体１０の内部空間１０Ｂは仕切られていなくてもよい。 In addition, in the packaging box 1 according to the first embodiment, the extension plate 15, the partition plate 16, and the joint piece 17 are provided, but this is not limiting and these may be omitted (not shown). In other words, the internal space 10B of the cylindrical body 10 does not have to be partitioned.

また、第１実施形態に係る包装箱１は、商品ケース９０の側面９４Ａに取り付けられるものであったが、これに限らず、包装箱１が単体で使用されてもよい。 In addition, the packaging box 1 according to the first embodiment is attached to the side surface 94A of the product case 90, but this is not limited thereto, and the packaging box 1 may be used alone.

Fig. 9 is a perspective view showing the packaging box 2. In the description of the packaging box 2 according to the second embodiment, the same reference numerals are used for the same or corresponding configurations as the packaging box 1 according to the first embodiment described above, and descriptions of the same or corresponding configurations as the packaging box 1 will be omitted. Also, the dashed lines shown in Fig. 8 indicate fold lines such as general-purpose creases and lead creases.

包装箱２では、一対の端板１１，１２と一対の側板１３とが、略四角形状の底板４０の周縁部に連設されている。一対の端板１１，１２と一対の側板１３とが交互に底板４０の周縁部に立設されることで、上端面（軸方向の一端）に開口部１０Ａを開口させた筒体１０が形成されている。一対の側板１３の前端には、一対（２つ）の継代板１４が連設されている。２つの継代板１４は、側板１３に対して内向きに折り曲げられ、前端板１１の左右両側の裏面に接合（接着）されている。各々の継代板１４の上方（軸方向の一方）には、前端板１１の上端（軸方向の一端）よりも上方（外側）に向かって突出する案内凸部２７が設けられている。 In the packaging box 2, a pair of end plates 11, 12 and a pair of side plates 13 are connected to the peripheral portion of a bottom plate 40 having a substantially rectangular shape. The pair of end plates 11, 12 and the pair of side plates 13 are alternately installed on the peripheral portion of the bottom plate 40 to form a cylindrical body 10 having an opening 10A on the upper end surface (one end in the axial direction). A pair (two) of transition plates 14 are connected to the front ends of the pair of side plates 13. The two transition plates 14 are bent inward relative to the side plates 13 and joined (glued) to the back surfaces of both the left and right sides of the front end plate 11. A guide protrusion 27 is provided on the upper side (one side in the axial direction) of each transition plate 14, protruding upward (outward) from the upper end (one end in the axial direction) of the front end plate 11.

一対の側板１３の後端には、一対（２つ）の内片４１が連設されている。２つの内片４１は、側板１３に対して内向きに折り曲げられ、後端板１２の左右両側の裏面に対向する。一対の側板１３の上端には一対（２つ）の内折板２２が連設され、後端板１２の上端には蓋板２０が連設され、蓋板２０の自由端には差込片２１が連設されている。各々の内折板２２が側板１３に対して内向きに折り曲げられた後、蓋板２０が後端板１２に対して内向き（前方）に折り曲げられて開口部１０Ａを閉じる（図示せず）。蓋板２０が閉じられる過程で、差込片２１は、２つの継代板１４および前端板１１に沿って筒体１０の内部に差し込まれる（図示せず）。 A pair of inner pieces 41 are connected to the rear ends of the pair of side plates 13. The two inner pieces 41 are bent inward relative to the side plates 13 and face the back surfaces of both the left and right sides of the rear end plate 12. A pair of inner folding plates 22 are connected to the upper ends of the pair of side plates 13, a cover plate 20 is connected to the upper end of the rear end plate 12, and an insertion piece 21 is connected to the free end of the cover plate 20. After each inner folding plate 22 is bent inward relative to the side plates 13, the cover plate 20 is bent inward (forward) relative to the rear end plate 12 to close the opening 10A (not shown). In the process of closing the cover plate 20, the insertion piece 21 is inserted into the inside of the cylinder 10 along the two transition plates 14 and the front end plate 11 (not shown).

図示は省略するが、蓋板２０が開口部１０Ａを閉塞した状態で、差込片２１は、Ｌ字状切目２０Ａの断面を内折板２２裏面に対向させている。また、係合凸部３１は、継代板１４の係合凹部２８に配置されている。２つの内折板２２は、開口部１０Ａを閉じた蓋板２０の裏面に対向する。 Although not shown, when the cover plate 20 closes the opening 10A, the cross section of the L-shaped cut 20A of the insertion piece 21 faces the back surface of the inner folding plate 22. The engagement protrusion 31 is also disposed in the engagement recess 28 of the transition plate 14. The two inner folding plates 22 face the back surface of the cover plate 20 that closes the opening 10A.

以上説明した第２実施形態に係る包装箱２によれば、継代板１４との干渉を抑制しながら差込片２１を筒体１０に円滑に差し込むことができる等、第１実施形態に係る包装箱１と同様の効果を得ることができる。 The packaging box 2 according to the second embodiment described above can achieve the same effects as the packaging box 1 according to the first embodiment, such as being able to smoothly insert the insertion piece 21 into the tube 10 while suppressing interference with the transition plate 14.

なお、第１および第２実施形態に係る包装箱１，２では、継代板１４の軸方向の端部において、案内凸部２７が幅方向の内側に突設され、係合凹部２８が幅方向の外側に相対的に凹設されていたが、本発明はこれに限定されない。例えば、係合凹部２８を省略し、継代板１４の軸方向の端部全体が案内凸部２７とされてもよい（図示せず）。この場合、蓋板２０の係合凸部３１（Ｌ字状切目２０Ａ）が省略されてもよい（図示せず）。 In the packaging boxes 1 and 2 according to the first and second embodiments, the guide protrusions 27 are provided at the axial end of the transition plate 14 so as to protrude inward in the width direction, and the engagement recesses 28 are provided relatively recessed outward in the width direction, but the present invention is not limited to this. For example, the engagement recesses 28 may be omitted, and the entire axial end of the transition plate 14 may be used as the guide protrusions 27 (not shown). In this case, the engagement protrusions 31 (L-shaped cuts 20A) of the cover plate 20 may be omitted (not shown).

また、第１および第２実施形態に係る包装箱１，２は、板紙で形成されていたが、本発明はこれに限定されない。包装箱１，２は、例えば、紙製の段ボールシートや樹脂製の板（シート）等で形成されてもよい。また、包装箱１，２の各部の寸法（幅、奥行き、高さ等）や形状、板紙等の厚みや紙目方向等は自由に変更してもよい。 In addition, although the packaging boxes 1 and 2 according to the first and second embodiments are formed from paperboard, the present invention is not limited to this.
